Stylomastoid foramen

Last revised by Dr Grace Carpenter on 02 Jan 2021

The stylomastoid foramen is a rounded opening at the inferior end of the facial canal. It is located on the inferior surface of the petrous temporal bone, between the base of the styloid process and the mastoid process of the temporal bone. It transmits the facial nerve and stylomastoid artery (branch of posterior auricular artery).
